The Wilcoxon signed-rank test is extremely efficient as you said and it is robust so I almost always prefer it over the t test If I understand it correctly - when comparing the location of two unmatched samples we would prefer to use the Wilcoxon rank-sum test over the unpaired t-test if our sample sizes are small. We can use this when. QUESTIONThe Wilcoxon signed-rank test is used to test which of the following types of hypothesesANSWERA It is used to test hypotheses involving the median.
